Description

长型网球拍 Long tennis racket

发明背景传统的网球拍的总长在26英寸至28英寸之间,目前大多数网球拍的长度约为27英寸。 BACKGROUND OF THE INVENTION Conventional tennis racket overall length of between 26 to 28 inches, most tennis racket about the current length of 27 inches. 至于为什么27英寸会成为工业上的标准尺寸,人们还不完全清楚,但是看来27英寸是制造具有灵活性并兼有稳定性的网球拍较适宜的长度尺寸。 As to why the standard size of 27 inches will be on the industry, it is not entirely clear, but it seems that 27 inches is manufactured with a tennis racket both flexibility and stability more appropriate length.

在英国专利No.2717(1909)和美国专利No.4,399,993中提出使用大于27英寸的更长尺寸来制造网球拍。 It proposes the use of a longer dimension greater than 27 inches to make tennis rackets in British Patent No.2717 (1909) and in US Patent No.4,399,993. 但是,增加长度的原因是为了能双手握持并挥动网球拍。 However, the reason is to be able to increase the length and waved both hands gripping a tennis racket. 这种网球拍势必是不便于使用且不具灵活性,而且这种需要双手挥动球拍的网球拍对于当今要求作出迅速反应使球拍快速运动以进行刁钻的接发球的网球运动是不甚适宜的。 This tennis racket is not easy to use and not bound with flexibility, and this requires both hands waving tennis rackets racquet for today's requirements to respond quickly to the fast movement racket tricky for tennis return of serve is not very appropriate.

相反,美国专利No.3,515,386提出,如果确需作改进的话,应该缩短传统的27英寸的网球拍的长度以提高网球拍的灵活性、可玩性和击球的命中率。 In contrast, US Patent No.3,515,386 proposes, if do need to make improvements, it should shorten the length of the traditional 27-inch tennis racket tennis racket to improve flexibility, playability and hitting percentage. 因此,该专利指出,对于众多的网球手来说,即使是27英寸的网球拍仍太长并缺乏足够的灵活性,并建议至少是对于某些网球选手来说应减小27英寸网球拍的长度。 Thus, this patent that for many of the tennis player, even a 27-inch tennis racket is still too long and lacks sufficient flexibility, and suggested that at least for some tennis players who should be decreased 27 inches tennis racquet length.

在过去的30年中,在网球拍的设计和材料上已有很多重大的发展。 In the past 30 years, there have been many significant developments on the tennis racket design and materials. 在1976年,采用了根据美国专利No.3,999,756制造的超长尺寸球拍,这种球拍使得网球运动更容易进行并使该运动的普及达到一新的阶段。 In 1976, using a long size racket made in accordance with U.S. Patent No.3,999,756, which makes the tennis racket easier to make the popular movement reaches a new stage. 网球拍的框架材料技术亦不断得到改进,从开始使用的木材到金属到逐渐使用复合材料。 Tennis racket frame material technology has also been improved continuously, beginning to use composites from wood to metal to start using. 自1980年起,复合材料,例如所谓的″炭精″,由于其具有较高的强度/重量比值,已成为用来制造高性能球拍的主要材料,以使球拍能制造得更轻并更具灵活性。 Since 1980, composite materials, for example, so-called "Carbon", because it has a higher strength / weight ratio, has become the main material used to manufacture high-performance racket so that the racket can be made lighter and more flexibility.

很多网球拍公司都试图推广比传统的27英寸长度更长的球拍,但都以失败而告终。 Many companies are trying to promote tennis racket longer than the traditional 27-inch length of the racket, but all ended in failure. 其主要问题是由于球拍的长度变长,使球拍更重并降低了它的灵活性。 The main problem is due to the longer length of the racquet, so that the racket heavier and reduces its flexibility. 这是在各网球拍公司制造、且网球手们又要求更轻型、更灵活的球拍的时代大潮中出现的问题。 This is a manufacturing company in the tennis rackets and tennis player who also requested more light, more flexible trend of the times racket arise.

本发明的概述本发明提供一种网球拍,它保持了当今流行的轻型网球拍的挥击重量,但其总长却大体上比目前的网球拍更长,即大于28英寸,并最好在29至32英寸之间。 Summary of the Invention The present invention provides a tennis racquet which maintains the swing weight of today's popular light tennis racquet, but it has an overall length substantially longer than the current tennis racket, i.e., greater than 28 inches, and preferably 29 to between 32 inches.

具体地说,本发明的网球拍的总长大于28英寸并包括一宽体框架、一单轴或双轴,以及一重量较轻的、最好为嵌入模内的球拍柄部。 Specifically, the total length of a tennis racket of the present invention is greater than 28 inches and comprises a widebody frame, a uniaxial or biaxial, and a lightweight, preferably embedded in the molded racket handle portion. 头部形成了一蛋形穿弦表面,其长度至少为14英寸,并最好在14至 A head portion formed egg shape strung surface a having a length of at least 14 inches, and preferably 14 to 英寸之间,并且其穿弦面积大于95平方英寸,最好在100至125平方英寸之间。 Between inches, and it stringing area greater than 95 square inches, preferably between 100 to 125 square inches. 框架由复合材料制成,并为宽体轮廓,从而使其每单位长度具有最小的重量。 A frame made of composite material, and for the wide-body profile, so that it has a minimal length per unit weight. 轻型框架与嵌入模内的球拍柄一起使用而使网球拍的穿弦重量保持在300克或更轻,从而使网球拍绕球拍柄的转动惯量不大于传统球拍,更具体地说不超过56克·米2。 Light racket handle frame for use with the mold embedded within the racket strung weight of 300 grams or less and held, so that the moment of inertia of the racket about the racket handle is not larger than a conventional racket, more particularly not more than 56 g · m 2.

更具体地说,本发明提供了一种网球拍,包括一具有头部的框架,该头部具有一构成含有诸弦的穿弦表面;一球拍柄:以及至少一个与所述头部和所述球拍柄连接的轴,其中,所述头部形成一个蛋形穿弦表面,该穿弦表面的长度至少为14英寸并且其穿弦面积大于95平方英寸:其中所述框架是一由复合材料构成的宽体的轮廓件;所述网球拍具有一大于28英寸的总长,具有不超过300克的穿弦重量,并且绕球拍柄的转动惯量不超过56克·米2。 More particularly, the present invention provides a tennis racket, comprising a frame having a head portion, the head portion having a strung surface containing the strings of a configuration; a racket handle: and at least one of the head and the said handle connected to the shaft of the racket, wherein the egg-shaped head portion forming a strung surface length of the stringing surface is at least 14 inches and which is strung area greater than 95 square inches: wherein said frame is a composite material widebody profile member formed of; a tennis racket having a total length greater than 28 inches, no more than 300 grams strung weight and moment of inertia about the racket handle is not more than 56 g · m 2.

具有上述结构的网球拍的长度较长,但是通过保持其挥击重量等于或小于传统型网球拍,这种网球拍仍具有良好的灵活性。 Longer length tennis racket having the above structure, but equal or less than conventional tennis rackets by maintaining its swing weight, such a tennis racket still has good flexibility. 作为美国公开专利No.07/922,930的主题内容的本发明的网球拍的蛋形框架,在结构上是在网球拍发展中最有效的头部形状。 As the subject matter of U.S. Patent Publication No.07 / 922,930 of the egg-shaped tennis racket frame of the present invention, it is structurally the most efficient head shape developed in the tennis racket. 这种形状减轻了球拍的重量并同时保持了良好的性能和控制性。 This shape reduces the weight of the racket, and while maintaining good performance and controllability. 嵌入模内的球拍柄,以及其中使用的单轴结构,也明显地减轻了球拍的重量。 Racket handle embedded in the die, and in which the single axis, but also significantly reduce the weight of the racket. 通过使用这种结构并由此沿框架减轻了球拍的重量,球拍的长度能得到延伸并同时保持与传统型球拍同样的挥击重量。 By using such a structure along the frame and thereby reduce the weight of the racket, extending the length of the racket can be obtained while maintaining a conventional racket of the same swing weight. 这种更长的网球拍具有很多使用优点,这将在下文中论述。 This use of longer racquet has a number of advantages, which will be discussed below.

本发明的网球拍提供了网球手更大的有效作用区。 The present invention provides a tennis racket tennis player more effective role area. 例如,比传统型27英寸网球拍长出2英寸的网球拍能提供网球手多出13%的球场可控范围。 For example, 27 inches than the traditional type of tennis racket tennis racket grow 2 inches can provide a tennis player more than 13% of the stadium manageable. 这是通过利用球体体积公式,V=4/3πr3,而计算得到的,其中,"r"是网球手的肩部至网球拍的顶端之间的距离。 This is the volume of the sphere by using the formula, V = 4 / 3πr3, and calculated, wherein, "r" is the distance between the shoulder and the top of the tennis racket hand. 对于一个身高为6英尺的人来说,r≈4英尺,故球场可控范围的体积(人仍保持站立)为268英尺3。 For a height of six feet of people, r≈4 feet, so that the volume of the controllable range of the pitch (kept standing still) is 268 ft. 使用长出2英寸的网球拍将能提供303英寸3的球场可控范围,或者多出13%的可控范围。 Using a 2-inch racket grow would provide 303 inches 3 stadium controllable range, or 13% extra controllable range. 该差值随网球手高度的减小而增加。 The difference with the decrease of tennis player height increases. 例如,一个身高为5'6"的人能获得14%的球场可控范围的增量。这种多出的可控范围能提供网球手极大的好处,特别是当网球手伸展手臂以大幅度截击空中球或收拢手臂大幅度发球时。这也意味着击中球的位置之间存在差异,即在球拍顶部(即传统的下能量区)击中球和在更接近网球拍面的中心处击中球之间的差异,网球拍面的中心处是能量最大的地方,因此在此处所击的球最有力。网球手不必过多弯曲他们的膝盖,因此对于老年网球手来说,这种球拍能更便于他们进行网球运动。 For example, a height of 5'6 "who can get manageable increments of 14% of the course. This extra controllable range can provide great benefits tennis player, tennis player especially when extending the arms to large this also means that there is a difference between the position of the ball when hit by the magnitude of volley ball or folded arms dramatically, and that is to hit the ball closer to the center of the racket face at the top of the racket (that is, under the traditional energy region) at the difference between hitting the ball, the center of the tennis racket is the surface energy of the largest local, so here hit the ball the most powerful. tennis player does not have to bend their knees too much, so for older tennis player, this kind of racket they can more easily be tennis.

这种较长的网球拍能在同样击球速率下提供网球手更多的力量,假定转动挥击速度保持恒定,网球拍撞击区处的切线速度与网球拍的长度成正比,假定球击触在离网球拍顶部6英寸处,长出2英寸的网球拍将产生高出10%的球拍头部速度,以及由此产生的10%的球速增加量。 This longer racquet provides at the same rate tennis player hitting more power, assuming rotational swing speed is constant, the tangential velocity at impact with the tennis racket region proportional to the length of the tennis racket, the ball hit the assumed contact six inches away from the top of the tennis racket, a tennis racket grow two inches will produce a 10% higher racquet head speed, and the resulting increase in the amount of 10% of the ball. 这意味着网球手能用同样的力量但能更便于控制地击球或者采用同样的击球方式但击出的球更有力。 This means that tennis players can use the same power but it can be easier to control the ball or hit the ball using the same way but hit the ball more effectively.

一种较长的网球拍能使更多的发球落在界内、更高的发球直接得分的机会。 One kind of long tennis racket can serve more falls within the sector, the higher the chance to serve directly score. 一种长出2英寸的网球拍能在指定发球区内开辟出多出13%的可利用区以便于中等身高的网球手大力发球。 One kind of tennis racket can grow 2 inches open up more than 13 per cent of the available area in order to serve and tennis player of average height in the designated tee area. 这是通过确定一角度而计算得到的,该角度的大小是由从发出刚好越过球网的球的触球点起算的初始轨迹角和一从发出刚好落在发球区内的球的触球点起算的初始轨迹角而确定的。 This is determined by a calculated angle, the size of the angle is the initial impact point trajectory angle starting from a point just touches the ball over the net and emitted from a tee area just fall emitted from the ball starting an initial trajectory angle determined. 在这两条线之间形成的角度是用于发球的角度窗并且随接触点高度的增加而增加。 The angle formed between these two lines is the angle window for the serve and with increased contact point height increases. 由于发球是网球运动中最为重要的击球技术,故这是其一项最主要的优点。 Since the tennis ball is the most important hitting skills, so this is one of its main advantages.

网球拍最好采用交错穿弦方法,其中诸弦的两端均倾斜从而交替地岔开在离开中心穿弦平面的两相反的方向上。 Preferably staggered stringing tennis racquets, wherein both ends of the strings are alternately inclined so as to diverge in the opposite directions on both strung in a plane away from the center. 这种交错穿弦方法的使用,特别是结合使用一蛋形头部,在球拍多出的长度以外又进一步有助于提供良好的可控性。 This staggered strings through the use of the method, in particular using an egg-shaped head joining, other than the extra length of the racket further helps to provide good controllability. 同时,通过交错设置诸弦孔,与传统穿弦孔图案相比,能降低由框架上的孔产生的框架强度的损失。 Meanwhile, compared to the strings through the staggered holes with conventional stringing hole patterns, it can reduce the loss of frame strength generated by the holes on the frame. 这使得所制成的框架与具有可比强度的传统型框架相比,其重量更轻。 This made such that the frame compared to the conventional frame having comparable strength, which is lighter in weight.

将单轴12连接于头部10的喉状接合处15的材料最好为最少从而使其重量为最轻。 Uniaxial material 12 is connected to the head portion 15 of the throat 10 is preferably joined to a minimum so that it is the lightest weight. 在喉状区内,构成穿弦面区22的底部的内框架表面52由一段弧构成,该弧以位于网球拍轴线36上的C1为中心,半径为R1。 In the throat region, constituting strung surface area 22 of the bottom surface of the inner frame 52 is composed of an arc, the arc is located on the tennis racket 36 axis C1 as the center, a radius R1. 半径R1是蛋形头部的最小半径。 Radius R1 is the minimum radius of the egg-shaped head. 内框架表面52在两点P1之间延伸,该两点位于轴线36的两侧上,与中心C1隔开一段轴向距离"dp1"。 The inner frame surface 52 extends between two points P1, two points located on both sides of the axis 36, spaced an axial distance "dp1" with the center C1.

喉状接合处15的外表面由一连接轴12上端的轴过渡区54和一连接头部10的两端的头部过渡区56构成。 The throat 15 engaging the outer surface of the connecting shaft 12 is constituted by an upper end of a shaft transition region 54 and a head portion connected to both ends of the head portion 10 of the transition zone 56. 轴过渡区54起始于诸点P2处,如同轴12的延伸部,因此诸点P2之间的间隔为轴的宽度。 Yuzhu shaft transition region 54 starting at the point P2, as a coaxial extension portion 12 so that the axis spacing between the points P2 width. 轴过渡区54由一以C2为中心、半径为Rr的弧构成,该中心所处的位置的轴向间距与诸P2的轴向间距近似相等。 A transition region from the shaft 54 ​​to the center C2, arc radius Rr configuration, in which the axial spacing of the center position P2 and the various axial spacing approximately equal. 轴过渡区延伸至点P3处。 Shaft transition region extends to a point P3. 在头部过渡区56内,喉状接合处的外表面紧随在一段曲线之后,从而使横截面宽度逐渐变细直至点P4处(头部起始处),该宽度与头部10的宽度相等。 In the head transition region 56, the outer surface of the throat of the joint immediately after a curve, so that the cross-sectional width tapers until point P4 (start of header), and the width is the width of the head portion 10 equal.

球拍柄14具有一传统的八角形横截面形状。 Racket handle 14 has a conventional octagonal cross-sectional shape. 这种球拍柄是所谓的"嵌入模内式"球拍柄,诸如在Prince Lite网球拍中使用的那种,其中复合框架件直接模制入球拍柄的模型形状内,而不是将一单独的手柄连接在轴上。 This racket handle is a so-called "mold-in" type racket handle, such as that used in the Prince Lite tennis racket, the inner shape of the composite frame member wherein the model is molded directly handle to score, rather than a separate handle attached to the shaft. 由于嵌入模内的球拍柄是中空的,球拍柄的重量为最小。 Due to the embedding within the molded racket handle is hollow, the weight of the racket handle to a minimum. 球拍柄14通常外包装有夹紧件(未示)。 Racket handle 14 typically have outer clamping member (not shown).

在公开的美国专利号为No.08/988,579的专利中揭示了一些可以用来形成单轴网球拍和喉状接合处15的工艺的例子,其中有关部分在本文中引为参考。 Some disclosed examples may be used to form a uniaxially tennis racket and a throat joint process 15, the relevant portions of which are incorporated by reference herein disclosed in U.S. Patent No. No.08 / 988,579 patents. 一种可以用来制造网球拍的工艺的例子将在下文中描述。 Examples of the manufacturing process may be used one kind of a tennis racquet will be described hereinafter. 由于通常用来制作复合式网球拍的模制技术作为已有技术已为公众所知,故对这种工艺只作简短的描述。 Because molding techniques commonly used to make composite tennis racquet as prior art are already known, so the process only for this short description.

请参阅图9。 See Figure 9. 一长度与球拍柄14和轴12相应的树脂浸渍增强材料管24由未塑化的纤维增强热固性树脂片(聚酯胶片)按常规方法制成。 12 and a corresponding axis length of the resin-impregnated racket handle 14 with the reinforcing fiber material of the tube 24 by a non-plasticized reinforced thermosetting resin sheet (prepreg) prepared by a conventional method. 一具有足够长度以构成头部10的第二树脂浸渍增强材料管34以类似方式制成。 Having a sufficient length to form a second resin impregnated reinforcing material 10 of the head tube 34 is made in a similar manner. 将该两管装入一网球拍的模具模腔内,从而使头部树脂浸渍增强材料管34的两端40延伸伸入材料管24的上端内一小段距离。 The two charged in a mold cavity of a tennis racquet, so that the head ends resin impregnated reinforcing material 40 of the tube 34 extends a short distance extending into the upper end 24 of the tube material. 为了构成喉状接合处15,将另外的未塑化合成材料26充填入喉状区域15内,并且用其它的复合聚酯胶片28将喉状接合处15包裹住。 In order to form the throat joint 15, additional inner material 26 is not filled with the plasticized synthetic choking shaped region 15, 28 and the throat joint 15 is wrapped by other composite polyester film. 一汽圈30向上直接穿过球拍柄的轴,绕头部材料管34一圈后,再通过球拍轴材料管的另一侧向下返回,从而使汽圈的两端从球拍柄14的底部伸出。 FAW ring 30 directly upwardly through the shaft of the racket handle, the head portion 34 in a circle around the tube material, and then back through the other side of the racket shaft material tube, extend from the bottom so that the racket handle ends 14 of the steam turns out.

然后合拢模具并向汽圈充气以使复合材料与模具的形状相一致。 Steam is then closed and the mold ring so that the inflated shape of the composite material and the mold coincide. 与此同时,加热模具从而使复合树脂塑化并变硬。 At the same time, so that the mold is heated and plasticized resin composite hardens. 为了制造嵌入模内式球拍柄,构成球拍柄14的模具部分(未示)具有一与图8所示的球拍柄14的八角形状相匹配的内表面。 In order to produce the racket handle mold insert, the mold configuration racket handle portion (not shown) having an inner surface with a racket handle shown in FIG. 8 octagonal 14 14 matches.

图9示出了一较佳实施例,其中头部10和轴12均为单独的构件。 Figure 9 shows a preferred embodiment in which the head portion 12 are separate members and the shaft 10. 头部10和轴12可由相同材料制成,也可由不同材料制成。 Head 12 may be made of the same material and the shaft 10, may be made of different materials. 同时,头部10和轴12可以是预成形部件而不是树脂胶片敷层。 Meanwhile, the head 10 and the shaft member 12 may be preformed instead of the resin coating film. 在头部和轴为预成形部件时,有必要仅仅模制并塑化喉状接合区以构成完整的框架。 When the head portion and the shaft member is preformed, it is necessary only plasticized molding and engage the throat zone to form a complete frame.

如图9所示,头部10的两相对端40被弯曲后边靠边地沿着头部10的中心轴线延伸一段预定的距离。 9, the two opposite ends of the head portion 10 is bent back by side 40 extends a predetermined distance along the central axis of the head 10. 这样头部10的两端40与材料26和28一起被插入轴12的上端以形成一稳固的头部与轴的接合区。 Such ends 40 of the head 10 with the material 26 and 28 along the upper end of the shaft 12 is inserted to form a firm bonding region of the shaft head.

如图9所示,喉状接合区15在轴12和头部10之间包括一相对陡峭的弯曲。 9, a throat region 15 between the engaging shaft 12 and the head portion 10 comprises a relatively steep bend. 其结果是,轴10的初始部分45以一相对于轴线36约为125°的角度延伸。 As a result, the initial portion 45 extends at an axis 36 with respect to an angle of approximately 125 ° of the shaft 10. 向上移动头部10,这一角度逐渐变小。 Upward movement of the head 10, this angle becomes gradually smaller. 但是,在整个起始长度上,头部10的轮廓件所承受的向平面外弯曲负荷主要是作为扭力。 However, over the entire length of the starting, the head profile member 10 is subjected to out of plane bending loads mostly as torsion. 因此,在本发明的一个较佳实施例中,为了提高框架起始部分的抗扭刚度,使构成框架部分45的聚酯胶片内的纤维的偏离角增大,并沿头部10增加一段所需附加距离。 Thus, in a preferred embodiment of the present invention, in order to increase the torsional stiffness of the initial portion of the frame, the frame constituting portion off angle fibers within the prepreg 45 is increased, and the head 10 increases along a section of the for additional distance. 此外,或作为替代,可再将加强部28裹住从而使加强筋有一偏置角度以增强抗扭刚度。 In addition, or alternatively, it may be again wrapped such that the reinforcement rib 28 has a bias angle to increase torsional stiffness.

在另一实施例中,头部10和轴12能由一种连续型树脂浸渍增强材料管制成。 In another embodiment, the head portion 10 and the shaft 12 can be reinforced with resin impregnated material a continuous tubing. 在这种情况中,轴12和球拍柄14将通过延伸形成头部10的管的两端而制成。 In this case, the shaft 12 and the racket handle 14 the ends of the tube head 10 is formed by extending made. 这种喉状区域15将以类似于图9的方式制成,使用加强材料26和28来构成一稳固的接合处15,除了构成头部的管子的两端穿过喉状区域之外,并且随后肩并肩地延伸在接合处15下方以构成轴和球拍柄而不是被插入在一如图9所示的单独的轴管内。 This throat area 15 will be formed in a manner similar to FIG. 9, 26 and 28 using the reinforcing material to form a strong joint 15, in addition to constituting the tube ends through the throat region of the head outside, and side by side and then extends below the junction 15 to form the shaft and handle rather than being inserted into the racket in a separate shaft tube as shown in FIG. 9 a. 当模制时,将在轴和球拍柄的内侧上形成中心壁,在该处邻靠有肩并肩的诸管。 When molded, the central wall formed on the inside of the racket shaft and handle, where all side by side abutment with a pipe. 为了减轻重量,最好在模制之后切除中心壁。 To reduce weight, the center wall is preferably cut after molding.

宽体框架框架具有一"宽体"轮廓,即具有一大于22毫米的横截面高度"h"(在垂直于穿弦平面的方向上)。 A body frame having a frame width "widebody" profile, i.e. has a cross section larger than 22mm and a height "H" (in the direction perpendicular to the stringing plane). 在这种较佳实施例中,框架轮廓的横截面高度"h"在25至26毫米之间。 In this preferred embodiment, the height of the frame between the cross-sectional profile of the "h" 25 to 26 is mm. 同时,在图1和图2所示的实施例中,头部10和轴12具有一恒定的横截面高度"h",头部10具有一恒定的宽度"w",并且头部10和轴12的高度和宽度可以根据需要改变。 Meanwhile, in the embodiment shown in FIG. 1 and FIG. 2, the head 10 and the shaft 12 has a constant cross-sectional height "h", the head 10 has a constant width "w", and the head 10 and the shaft 12 height and width may be varied as desired.

交错弦头部10包括一些用来接纳诸弦的孔34。 Interleaving string head portion 10 comprises aperture 34 for receiving the strings. 从图2和图10中可以清楚地看到,这些孔不是位于中心穿弦平面37内,而是相互交错以交替地位于平面37的相对两侧上。 It can be clearly seen in FIG. 2 and FIG. 10, these holes are not located in the center 37 through the chord plane, but mutually staggered alternately positioned on opposite sides of the plane 37.

请参阅图1和图4。 See Figures 1 and 4. 主弦26包括一对其位置离穿弦表面的几何中心GC最远的、处于两对置位置上的弦30;同样,交叉弦包括一对离几何中心最远的弦32。 26 comprises a main string stringing surface from its position of furthest geometric center GC, in the chord on the opposed position 30; similarly, the cross strings include a pair of strings furthest away from the geometric center 32. 在与框架头部13啮合之前,这些最远弦30、32中的每一弦构成了相应交叉弦或主弦的最后相交叉的弦。 Prior to engagement with the head frame 13, as far as these strings 30, 32 each chord constituting the corresponding cross string or main string last crossing string.

请参阅图10,可知用于交叉弦的诸孔40交替地位于中心平面的两相对侧上,从而能产生一交错的弦图案。 Please refer to FIG. 10, it is understood for the holes on the two opposite sides of the cross strings 40 are alternately located in the center plane, thereby to produce a staggered string pattern. 所有的交叉弦28和主弦26最好均采用交错穿弦方法。 All cross strings 28 and main strings 26 are preferably staggered stringing method. 如图10所示,诸弦孔最好均与中心穿弦平面37隔开一恒定的距离,从而产生一种恒定的交错排列。 As shown, preferably both with the central hole through the strings 10 chord plane 37 spaced a constant distance, resulting in a constant staggered. 或者,也可使用其它方式的交错穿弦图案。 Alternatively, other means may be used in staggered stringing patterns.

请参阅图4,该图示出了用于两连续交叉弦28a和28b的交错穿弦方法,两交叉弦中的第一弦28a延伸经过最远的主弦30,并随后直接与框架头部14啮合,穿过索眼40a,该框架头部延伸穿过一对形成在中空框架上的弦孔40a,该弦孔位于中心穿弦平面37的下方。 Please refer to FIG. 4, which shows two successive cross strings 28a and 28b strung interleaving method, the two cross strings 28a extending through the first string furthest main string 30, and then directly to the frame header 14 are engaged, through grommet 40a, which extends through a pair of head frame string holes 40a formed in the hollow frame, which is located in the center string holes 37 through the lower chord plane. 从而,交叉弦28a与最远的主弦30啮合成一小于180°的β角。 Thus, the cross string 28a farthest major chords 30 at an engagement angle β smaller than 180 °. 弦28a穿过弦孔40a并进入穿弦凹槽18,在穿弦凹槽处该弦穿过中心平面37而进入弦孔40b。 String 28a passes through string hole 40a and enters the stringing groove 18, in the stringing groove at the center plane passing through the chord 37 into the string holes 40b. 自弦孔40b起,下一根交叉弦28b在最远的主弦30下方延伸,并随后向下延伸与下一根主弦(未示)啮合。 Since the string from the hole 40b, the next cross string 28b extends in a downward furthest major chord 30, and then engaged with the downwardly extending lower chord a master (not shown). 为了清晰起见,在图4中稍稍放大了由交叉弦28a和28b朝着穿弦表面的中心(即朝着图4中的右侧方向)岔开的角度。 For clarity, in FIG. 4 is slightly enlarged by the cross strings 28a and 28b toward the center of the stringing surface (i.e. toward the right direction in FIG. 4) diverging angle.

关于如图2-5所示的另一实施例的穿弦结构,可以采用其中没有一根交错弦的传统型穿弦图案,一些弦可以被交错,而另一些没有被交错,或者交错排列的数量可以围绕头部在不同的位置变化。 Strung on the structure of another embodiment shown in FIG. 2-5 embodiment may be employed which is not a traditional interleaved strung string pattern, some of the strings may be staggered, while others are not interleaved or staggered the number of heads may vary in different locations around.

交错穿弦的使用提高了弦床的性能。 The use of staggered stringing improves the performance of the string bed. 而且提高交错设置弦孔,与传统型弦孔图案(所有的弦孔均排成直线)相比,增加了相邻孔之间的间距。 Further increase staggered string holes, as compared to conventional string hole patterns (all the string holes are aligned), to increase the spacing between adjacent holes. 这意味着由框架上的成形孔产生的强度的损失比传统型网球拍要小。 This means that the loss of strength resulting from the molding hole of the frame is smaller than conventional tennis rackets. 因此,本发明的框架能比传统型框架(即使用较少的材料)制造得更轻并且仍保持同样的强度。 Accordingly, the present invention can be a frame type than the conventional frame (i.e., using less material) made lighter and still maintain the same strength.

图11示出了另一实施例,其中头部10a通过一对会聚轴部12a而连接于球拍柄14。 FIG 11 shows another embodiment, wherein the head portion 10a by a pair of converging shaft portions 12a connected to the racket handle 14. 一喉状桥15a横跨过轴部12a从而构成一完整的穿弦区。 A throat bridge 15a spans the shaft portions 12a through thereby forming a complete strung area. 但是,如图1所示的实施例中,头部为蛋形,在六点钟位置处具有一小于位于12点钟处的半径R4的半径R3。 However, as illustrated in Example 1, the head is egg-shaped, having a radius of less than 12 o'clock located at R3 and R4 at the six o'clock position. 从P3至P2,框架件紧随在一段半径为RT的曲线后,并且位于两轴12a之间、位于喉状桥15a下方的区域是敞开的。 From P3 to P2, the frame member in a period immediately after a curve radius RT and is located between the two shafts 12a, located in the area below the throat bridge 15a is open. 如图11所示,一平头盖50最好封住球拍柄14的底端,并且一夹紧件52包裹在八角形球拍柄14的外侧以构成一完整的网球拍。 11, the cap 50 is preferably a flat bottom end 14 to seal the racket handle, and a clamping member 52 the shank outer wrap 14 to form a complete tennis racket octagonal racket.

总之,本发明的网球拍的总长大于28英寸,最好在29至32英寸之间,采用一具有大于14英寸的最小长度的蛋形框架,以及一最好嵌入模内的轻型球拍柄。 In short, the total length of a tennis racket of the present invention is greater than 28 inches, preferably between 29 to 32 inches, use of an egg shape frame having a minimum length greater than 14 inches, and preferably embedded in a lightweight molded racket handle. 结合使用一具有这种形状的框架,通过使用薄壁部分和宽体结构(高度大于22毫米,纵横比大约为2/1或更大),该框架应该能制造得重量较轻。 In conjunction with a frame having such a shape, through the use of thin-walled portions and wide structure (height greater than 22 mm, an aspect ratio of about 2/1 or more), the frame should be made light in weight.

通过采用上述形状,并采用目前市场上供应的材料,有可能使制造出的网球拍的重量基本上小于300克,并且最好近似为250克,其中较长的弦床不具有蹦床效果,并保持良好的性能和控制性。 By adopting the above shape, and the use of materials are currently available on the market, it is possible to make the weight of the racket to produce substantially less than 300 grams, and is preferably approximately 250 grams, which does not have a longer string bed trampoline effect, and to maintain good performance and control. 这产生了增加网球拍总长的能力,同时保持了传统高性能网球拍的使用上的优点。 This creates the ability to increase the total length of a tennis racket, while maintaining the advantages of using a conventional high performance tennis racquet. 在总重量和绕球拍柄的转动惯量达到传统型网球拍的相应值之前,网球拍的长度能被基本上提高。 Prior to the total weight and moment of inertia about the racket handle reaches a value corresponding to the traditional tennis racket, a tennis racket length can be substantially improved. 因此,这种网球拍使用起来感觉上类似于传统型网球拍,但是在实际上,增加的长度将提供明显的使用上的优点。 Thus, use of such a tennis racket feel similar to traditional tennis racket, in fact, increased length will provide significant advantages in use.

为了进一步提高网球拍的可玩性,惯性极量(绕网球拍的纵轴转动的转动惯量)应该小于1.90克·米2,并最好在1.6-1.7克·米2之间,并且平衡点(重心)应该位于自平头端起至少13.4英寸的地方。 To further improve the playability of inertia of the racket maximal (rotation about a longitudinal axis of the racket inertia) should be less than 1.90 g · m 2, and preferably between 1.6-1.7 g · m 2, and the balance (center of gravity) should be located from local grub reach of at least 13.4 inches. 如以上指出的,穿弦表面的长度应该大于14英寸,并且对于复合式网球拍来说,框架最好具有140赫兹的最小自由空间频率。 As noted above, the strung surface length should be greater than 14 inches, and for a composite tennis racket, the frame preferably has a minimum free space frequency of 140 Hz. 框架的横截面宽度最好为12.5毫米。 Preferably cross-section of the frame width of 12.5 mm.

如图5、图7和图8所示,头部10、轴12以及框架的球拍柄14由例如复合材料模制成的中空轮廓件制成。 5, 7, and 8, the head 10, shaft 12 and the racket handle frame member 14 is made of a hollow profile made of a composite molding, for example. 除了在喉状接合处上之外,轮廓件具有最好小于2毫米的最小壁厚以减轻重量。 In addition to the throat joint, the profile members have minimum wall thickness is preferably less than 2 mm to reduce weight. 在框架上任一给定位置的壁厚最好随可能受到的弯曲应力而变化。 Office vary frame to a bending stress preferably with a wall thickness of a given location may be subjected.

网球拍可以使用一种热塑性材料进行制造。 Tennis racket can be manufactured using a thermoplastic material. 可用编织加强纤维和热塑性细丝的套管来代替形成热固性树脂的敷层,如美国公开专利号为No.5,176,868的专利中所揭示的那样。 Cladding layer may be woven reinforcing fibers and the thermoplastic filaments forming the sleeve instead of the thermosetting resin, as disclosed in U.S. Patent No. Patent No.5,176,868 as disclosed in. 此外,还可用纤维和细丝混合材料作为加强部分26、44以及喉状接合处15的包裹层28、46。 Further, the fibers and filaments can also be used as a wrapping material mixture layer portions 28, 46 joined at 26, 44 and the throat 15 of the reinforcement.

通常,根据本发明制造的网球拍绕重心具有更高的转动惯量(除了重量极重的Matchmate和Ray网球拍除外)。 Typically, around the center of gravity of the tennis racket in accordance with the present invention have a higher moment of inertia (except for extremely heavy weight except Matchmate Ray and tennis rackets). 因此,对于沿中心轴线离开中心击球点来说,这种网球拍比传统型较轻的网球拍更稳定。 Thus, along the central axis away from the center for the impact point, this racket is more stable than traditional tennis racket lighter.

因此,如图12所示,本发明的网球拍较轻,但较稳定,这样将网球拍的诸多所期望的优良特征中的两种特征,灵活性与稳定性结合起来。 Thus, as shown in FIG. 12, a tennis racket according to the present invention is lighter, but stable, so that the combination of two features superior characteristics desired in many tennis racket, flexibility and stability. 相反,在传统型网球拍的设计中,通常只能在网球拍的这两种特征中选择一种。 In contrast, the traditional tennis racket design, usually only choose one of these two features in a tennis racket.

进一步如图12所示,根据本发明制造的网球拍经测试具有在任一种网球拍中均为最高的撞击中心。 As further shown in FIG. 12, any of a tennis racket having both the highest center of percussion of the racket was tested in accordance with the present invention is manufactured. 如在此处所使用的,撞击中心是围绕平头端测得的。 As used herein, center of percussion is measured about the butt end. 此外,撞击中心与网球拍重量的比值明显大于本发明的网球拍。 Further, the center of percussion and the ratio by weight of the tennis racket of the present invention is significantly greater than a tennis racket.

通过使撞击中心远离手,网球拍在其撞击中心和喉部之间具有一极其适合击球的区域。 By hand away from the center of percussion, a tennis racket having extremely suitable batting area between its center of percussion and the throat. 通常,当球击中在撞击中心和手之间时,击打的感觉是非常坚实的。 Typically, when the ball hit between the center of percussion and hands, hitting feeling it is very solid. 相反,当球击中在撞击中心和网球拍的顶部之间时,打球的人通常感觉上球的冲击较大,而球反弹的能量较低。 On the contrary, when the ball hit the top of the impact between the center and tennis rackets, playing usually feel a greater impact on the ball, and the ball rebound energy is low.

在本发明的网球拍中,振动的上节点的位置位于比传统型网球拍自其平头端至上节点的距离更大的位置处,如图13所示(除了较长且较重的Ray网球拍之外)。 In the tennis racket of the present invention, the position of the node of vibration is located at a distance from the racket than the conventional type of nodes for which a larger butt end oriented position shown in Figure 13 (except that longer and heavier Ray tennis racket outside). 因此,该节点与网球拍顶端的距离与传统型网球拍自其顶端至节点的距离近似相等。 Thus, the node with the distance from the top of the tennis racket conventional racket distance from its tip is approximately equal to the node. 如果仅仅加长传统型框架的长度,且头部仍保持同样的尺寸,该节点将朝着网球拍的平头端的方向移动,这使得节点位于头部的较下处(减小“灵活区域”(sweet spot)的尺寸)。 If the length is longer only traditional frame, and the head remains the same size, the node would move toward the butt end of the racket, which makes the head node is located more Xiachu (reduced "flexible region" (Sweet SPOT) size). 通过在已有技术的网球拍上进行测量,这已经得到了证实,在这种已有技术的网球拍上,节点的位置已经明显地比使用相似头部形状的传统型网球拍进一步远离网球拍的顶端。 By measuring tennis racket prior art, it has been confirmed, the tennis racket in this prior art, the position of the node is already significantly longer than using a similar head shape further away from conventional tennis racket tennis racket top. 在本发明中,振动的上节点的位置与球拍手柄端的距离大于弦床长度的57%。 In the present invention, the position of the node of vibration from the handle end of the racket is greater than 57% of the chord length of the bed.
